Rinnai is introducing the updated Rinnai E-Series early in 2025 with the 17CE Condensing External Water Heater. This upgrade ensures UK customers can benefit from the latest advancements in hot water heating technology.

Each unit is designed to reduce customer costs and provide continuous hot and clean water upon demand. The gas-fired water heaters are lightweight so there is no need for heavy lifting gear. The continuous flow water heaters are powerful yet diminutive with a max flowrate of twenty litres per min making them an ideal water heating solution where space is limited.

Inclusion of microprocessors enables the customer to pre-set water temperature delivered accurately to +1 / -1 degree of the set point helping eradicate legionella proliferation and delivery temperature inaccuracies that can create discomfort or scalding.

Rinnai’s continuous flow hot water systems will only use the required amount of energy to increase water temperature whilst supplying multiple litres of clean hot water. Continuous flow systems do not require energy consumption whilst not in use, meaning that the customer does not pay any costs when the system is not operational.

Both models – the 17CE are an ideal solution for glamping sites, leisure facilities, festival ablutions, small commercial outlets and where there is a requirement for cost effective and durable condensing water heaters.

The 17CE model weighs just 18kg and the unit is compact ensuring easy installation that requires far less space than alternative systems. The range of temperature is between 37 and 65 degrees Celsius, whilst hot water delivery capacity is twenty litres per minute. Gross efficiency is measured at 93%. Further additions include direct electronic ignition and frost protection.

The 17CE condensing water heater is a Bio-LPG ready water heater and the Natural gas continuous flow water heater is I2HY20 ready for Hydrogen blends of 20%. The range of temperature is between 37 and 65 degrees Celsius. Hot water delivery capacity is seventeen litres per minute.

Rinnai understands the UK customer requirement for cost effective and robust appliances that consistently deliver clean hot water and heating to domestic and commercial buildings across the UK. Rinnai are committed to offering UK customers low cost and practical solutions that cover all energy options.

creating a healthier way of living

 

 

 

Rinnai’s Tony Gittings calls for industry unity in delivering practical, economic and technical benefits of decarbonisation

 

 

For UK decarbonisation aims to be successfully achieved a shared and consistent approach must be formulated and agreed upon by all acting parties within the HVAC and building services industries. At present there is widespread preference towards heat pump technology by mainstream media, and other interested groupings toward consumers and customers seeking clean and alternative methods of home or commercial property heating and hot water delivery.

 

Fact, logic and reason must be employed to achieve optimum practical, economic & technical outcomes for all of us. We need decarbonisation, we need NetZero, and we need it as soon as possible but in such a way that is pragmatic in terms of catering to the existing populations and markets.

 

To further encourage decarbonisation the industry must look past just simple financial motivation. No one single product alone is presently capable of delivering NetZero, so rather than fracture into competing groups, the heating & hot water sector will benefit from a platform of cross-communication and information sharing that can be relayed to positively assist the UK end-user and customer.

 

We need to look at this from the consumers’ viewpoint. We need to be putting accurate information in the public arena. At the moment there are a lot of interested bodies and companies showing understandable self-interest in wanting to know they have a future in the marketplace.

 

In our sector we have manufacturers of similar or like-for-like products which are looking to what will replace natural gas as the fuel of mass consumption and how that will affect them. We also have the pragmatic logic of trying to find affordable fuels for the mass market. Alternatives on their own are simply not an answer. We also need to look at the range of innovations and developments such as Hydrogen, BioLPG and rDME that will come on stream.

 

Yes, individual products have a place. But what would be the NetZero answer, as an example, to a commercial or industrial unit or site that has the added complications of needing Legionella prevention regimes and constant high temperature hot water in large volumes. How would electrification and heat pumps, for example, be attractive in terms of capital, installation and ongoing operational costs and performance?

 

Everything has a role to play and everything non-carbon can have a future. And a collective, equable effort will give us the result we all want, the result we must have, if we are to have a sustained quality of life.

 

We are a business based on engineering excellence and are employing technological creativity to achieve the targets. It will mean, in the UK, that we begin to offer a wider range of products under the H3 umbrella of Hydrogen, Heat Pumps and Hybrid Systems to enable our customers to achieve their own carbon reductions and eventual neutrality. Our product has been re-formulated to allow customer choice for every type of site and application. The range includes the following:-

 

H1 – Hydrogen, BioLPG – water heaters & boilers

 

H2 – Hybrid Systems – Heat Pumps and Solar Thermal

 

H3– Heat Pumps – Low GWP

 

It is possible that all residential and commercial sites can provide customers with heating and hot water systems that produce the most practical, economic and technical solutions – on and off grid.

 

Progress in decarbonisation requires common sense and a reduction of partisan beliefs regarding specific heating products, energy vectors and platforms. For example, heat pumps, if you listened, watched and read BBC content, are the sole answer to Net Zero. It would appear that no other product or system exists.

 

Heat pumps are the right product – but in specific circumstances. A site hoping to install a heat pump must be accurately evaluated so that the correct size heat pump is deployed. Load demand and seasonal adjustments must be made realistically based on past data. The aim must be to both maximise and optimise a whole system, no matter what type of building or property.

 

NetZero ambitions can be truly delivered if a measured, pragmatic and transparent stance is adopted by all players in the heating and hot water industry.

 

The manufacturing sector of the heating and hot water industry has a responsibility in playing a leading role in the reduction and eventual removal of harmful emissions. For UK decarbonisation targets to be met transparent assessments of product impact and efficiency should be common currency. To enact a national energy transition towards green energy there is a pressing need for unity of purpose across multiple industry sectors.

RETRO-FIT PROJECT FUTUREPROOFS BY REPLACING TRADITIONAL STORAGE WITH
HYDROGEN BLENDS READY CONTINUOUS FLOW WATER HEATERS

 

NEW SYSTEM YIELDS

30% REDUCTION IN CARBON EMISSIONS

90% INCREASE IN PLANTROOM SPACE

PROJECTED OPERATIONAL SAVING OF 21%

 

 

Rinnai N Series Hydrogen Blends ready 20% continuous flow water heaters have replaced a direct-fired hot water heating system at a state-owned site in South Wales which needed lower carbon and had a requirement for temperature accurate hot water to minimise any potential Legionella risk.

Six Rinnai N Series 1600i units were installed on a cascade frame to yield almost 6,000 litres of temperature accurate hot water per hour at 50 degrees C. The system included Rinnai UK’s Smart Remote Monitoring System for BMS Integration and common header flue system to streamline installation.

“All works were carried out and completed on time and to the very highest of standards. This state-owned site has a high foot fall through the building and so needs on demand hot water first time, every time,” says Ricky Lewis for Rinnai.

The Rinnai N Series is i2HY20 certified and is a high-performing condensing water heater delivering temperature accurate, limitless hot water. The N Series gas fired water heaters can be powered by a blend of up to 30% hydrogen, and work on BioLPG as a drop-in solution for any off-grid site. The appliance is described as ‘out of the box’ design engineered and approved to be installed for use on blended gas.

All Rinnai N Series units are guaranteed to provide limitless volumes of temperature accurate hot water flows, provided fuel and water connections are constant. The Rinnai Sensei N Series is the first ever continuous flow hot water heating unit manufactured with stainless steel heat exchangers to be available in the UK – this gives a greatly extended working life at optimum performance to each of the four models in the range. Added to this are the market leading extended warranties, that accompany these hydrogen ready appliances.

The four models of the Rinnai N Series are: the N1600i giving 954 litres per hour; the N1600e (external) also giving 954 litres per hour (at 50 degrees); the N1300i giving 775 litres per hour and the N1300e also giving 775 litres per hours of temperature-controlled water at 50 degrees. The two 1600s have load profiles of XXL and are water efficiency class A rated, while the 1300s are load profile XL and are also water efficiency class A rated.

The range is also low-NOx less than 26ppm and the futureproofed continuous flow water heaters have several global patents on main components. The range utilises Rinnai’s patented advanced technology with a 13-1 turn down ratio – the largest on the market – with extremely quiet operation.

Integral controls on the units enable the water heater to achieve high efficiencies because of advanced burner control and high modulation ranges. This wide range of modulation means that energy usage is completely optimised as the water heater, through smart inbuilt controls, will only heat the water to the temperature required, thus preserving energy.

 

Other features include:

  • Flue up to 30+ metres for concentric
  • Turbo Fan
  • Built-in controller as standard on both internal and external models
  • Cascade Cable assembly allows up to 24 water heaters to be connected and function as one total and complete system. Any number of N-series Rinnai water heaters can be manifolded together enabling the largest capacities on the market.
  • Built in flue damper
  • Air inlet filter
  • Frost Protection – minus 15°C on the internal versions and minus 20 °C on the external versions
  • New PCB Design
  • Controller as standard – Lockable, set up of appliance, Temperature set up to 75°C
